Objective: The current study was to compare the psychometric properties of the 25-item version (CD-RISC25), 10-item Connor-Davidson version (CD-RISC10) and 2-item Connor-Davidson version (CD-RISC2) in rehabilitation patients after injury.Method: A sample of 115 Chinese patients was measured by CD-RISC25, CD-RISC10 and CD-RISC2, PTSD Checklist-Civilian Version (PCL-C) and Symptom Checklist-90-Revised (SCL-90-R) during the rehabilitation period.Result: (1) Cronbach's alpha values indicated sufficient and high reliability to provide confidence in interpreting the score for the three versions; (2) The resilience measured by CD-RISC25 and CD-RISC10 both correlated negatively and significantly with PTSD and mental health problems, while this was not observed when resilience was measured by CD-RISC2; (3) Through ROC curves analyses, the CD-RISC25 and CD-RISC10 had similar discrimination for positive/negative group of SCL-90 and PTSD/non-PTSD.
Conclusion:The results supported the application of CD-RISC10 in clinical researches due to its excellent psychometric properties and time efficiency.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
